The alleged title takes place on a moon called Elpis during the five-year gap between Borderlands 1 and 2, and will be a four-player co-operative shooter like the previous two games in the series.

It follows Handsome Jack hunting for an alien artifact, back when he was a programmer named John. Players assume control of one of Jack's four lieutenants - Athena the Gladiator, Wilhelm the Enforcer, Nisha the Lawbringer and a militarised claptrap known as Fragtrap.

The prequel reportedly boasts two new weapon types, laser weapons and cryo - the latter of which has freezing properties, allowing players to shatter enemies.

Being on a moon, the game features gunfights in reduced gravity, while oxygen levels must be managed in order to stay alive and breathing.
